Given Numbers are 231, 235

We can find the LCM of 231, 235 using the brute force method, prime factorization method, or GCD method.

To use brute force method, list the multiples of 231 and 235

Multiples of 231 =231,462,693,924,1155,1386,1617,1848,2079,2310,2541,2772,3003,3234,3465,3696,3927,

Multiples of 235 =235,470,705,940,1175,1410,1645,1880,2115,2350,2585,2820,3055,3290,3525,3760,3995,

Now, get the least common multiple of 231, 235 which is 54285

So, the LCM of 231, 235 is 54285.

One method for determining the LCM of 231 and 235 is to compare the prime factorization of each number. You can find the prime factorization for each number by following the instructions below:

Here is 231's prime factorization:

Prime factors of 231 are 3, 7,11.

231 = 3¹×7¹×11¹

And this is 235's prime factorization:

Prime factors of 235 are 5,47.

235 = 5¹×47¹

When comparing the prime factorization of these two numbers, look for the highest power to which each prime factor is raised. In this case, the following primary factors must be considered: 3, 7,11, 5,47

3¹×5¹×7¹×11¹×47¹ = 54285

This shows that the LCM of 231 and 235 is 54285.

The first step in determining the Least Common Multiple of 231 and 235 is to generate a list of multiples for each number.

Lets look at the multiples of these two numbers, 231 and 235:

Lets look at the first ten multiples of these numbers, 231 and 235:

231,462,693,924,1155,1386,1617,1848,2079,3927 are the first ten multiples of 231.

235,470,705,940,1175,1410,1645,1880,2115,3995 are the first ten multiples of 235.

You can continue to list the multiples of these numbers until you find a match. Once you have found a match, or several matches, the Least Common Multiple is the smallest of these matches. The first matching multiple(s) of 231 and 235, for example, are 2772, 3927, and 3760. 54285 is the least common multiple since it is the smallest.

231 and 235 have an LCM of 54285.

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 231 and 235, than apply into the LCM equation.

GCF(231,235) = 1
LCM(231,235) = ( 231 × 235) / 1
LCM(231,235) = 54285 / 1
LCM(231,235) = 54285
